Description
I/O
1
SS:
Soft start terminal.
When V
CC
is applied, the capacitor connected to
this pin is charged, and the output duty is de-
creased by inputting the capacitor voltage to the
PWM.
(11)
2
RT:
The terminal for connecting a resistor to deter-
mine the charge and discharge current of the
triangular wave.
(12)
3
CT:
The terminal for connecting a capacitor to gener-
ate the triangular wave.
(13)
4
CLM(
):
The input terminal for pulse-by-pulse overcurrent
protection. It is usually required to attach an ex-
ternal filter.
